With the emergence of stretchable electronic devices, there is growing interest in the development of deformable power accessories. Herein, a poly(styrene-b-butadiene-b-styrene) block copolymer-based stretchable separator membrane was fabricated by the nonsolvent-induced phase separation (NIPS). The diversity of mechanical properties and porous structures can be obtained by using different polymer concentration and tuning the affinity among major components of NIPS. The stretchable separator exhibited a high stretchability of around 270% strain and porous structure having porosity of 61%. Thus, its potential application as a stretchable separator for deformable energy devices was demonstrated by applying to LIBs |
